International Day for the Preservation of the Ozone Layer

International Day for the Preservation of the Ozone Layer

The International Day for the Preservation of the Ozone Layer is an annual event dedicated to raising awareness about the importance of preserving the Earth's delicate ozone layer. The observance aims to educate individuals about the causes and consequences of ozone depletion as well as underscore the significance of global cooperation in tackling this pressing issue. Additionally, the day highlights the achievements made by signing and implementing the Montreal Protocol, an international treaty designed to protect the ozone layer by phasing out harmful substances responsible for its depletion.

The history and celebration of this important day are closely tied to South Africa's commitment to environmental protection and sustainable development. The country has joined the global agreement to protect stratospheric ozone layer, Montreal Protocol, in 1990. Since then it has played an active role in global efforts to reduce the production and consumption of ozone-depleting substances. South Africa has also taken various actions to regulate and monitor the use of these substances on a national level, ensuring compliance with international standards and promoting environmental conservation.

In observance of the International Day for the Preservation of the Ozone Layer, various activities and events take place across South Africa. These include educational campaigns, workshops, conferences, and community-based initiatives that aim to inform South Africans about the importance of the ozone layer and stress the crucial role of individual action in protecting it. Furthermore, the South African government may also undertake additional efforts to promote awareness and encourage adherence to environmental regulations. The International Day for the Preservation of the Ozone Layer is celebrated annually on September 16th, coinciding with the day that the Montreal Protocol was signed in 1987.

Facts about the Ozone Layer

• The theme for International Day for the Preservation of the Ozone Layer in 2025 was Montreal Protocol: Advancing Climate Action. In 2024 the theme was Montreal Protocol: fixing the ozone layer and reducing climate change.
• The natural level of ozone in the stratosphere is a result of a balance between sunlight that creates ozone and chemical reactions that destroy it.
• The thinning of the ozone layer is caused by chemicals, such as chlorofluorocarbons (CFCs), carbon tetrachloride, halons, and others. These chemicals -- often used in refrigeration, air conditioning, packaging, insulation, aerosols, and so on -- release chlorine and bromine when they come in contact with sunlight. These elements then deplete the ozone layer.
• The preservation of the ozone layer is crucial for maintaining a healthy environment, preventing skin cancer, and reducing the effects of climate change.
• According to the World Meteorological Organization, the Antarctic ozone hole is slowly recovering and is projected to be fully healed by the middle of this century with the help of international efforts and increasing use of climate-friendly substances.
